ISAIAH M. FURBISH, OF AUGUSTA,

PATENT OEEIcE.

MAINE, ASSIGNOR TO WILLIAM H.

JOHNSON, OF MELROSE, MASSACHUSETTS.

MECHANICAL MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 233,147, dated October12, 1880.

Application filed May 27, 1880.

To all whom it may concern Be it known that 1, IsAIAH M. FUEBIsH, ofAugusta, in the county of Kennebec and State ot' Maine, have invented anew and useful Improvement in Organettes 0r Mechanical MusicalInstruments, of which the following is a specilication.

The invention relates to the relative position ofthe wind-moving bellowsot' the above class of musical instruments to each other and means forworking the same.

Heretofore the small or wind-moving bellows have been arranged side byside at one end ot' the organette, and have been operated by a rotaryshaft having crank-bends thereon and links connecting with the bellows,the rotary shaft being connected with the drivingshaft by pitman-rods ateither end.

The objectof my invention is to do away with the rotary shaft and linksconnecting the same with the wind-moving bellows, which are liable toget out of order; and, further, to arrange the wind-moving' bellows soas to work by pitman-rods connected directly with the driving-shaft, andto increase the number of the wind-moving bellows without occupying anymore space than in the old arrangement, and with a corresponding'increase in power.

The invention consists in the arrangement ot" the wind-moving bellows byplacing` a pair ot' them upon each side of the large bellows orreservoir, so that the hinges ot' each pair adjoin each other, thereservoir being between the pairs and all ruiming lengthwise of theinstrument. The bellows of each pair are connected together by a rigidbrace, so that when one of the bellows is depressed the other iselevated.

It also consists in connecting the pitmanrods on each end of thedriving-shaft directly with the rigid brace, near its end, instead oi'to the rotary shaft, and of placing the pitmanrods on the inside of thecasing of the instrument, thereby greatly improving the outward beautyof it.

^ In the accom panyin gdrawin gs, in which similar letters of referenceindicate like parts, Figure 1 is a perspective view of the bottom of anorganette, showing my arrangement of the wind-moving bellows and meansfor working the same. Fig. 2 is a plan of the top of the wind-chest ofan organette, showing the driving-shaft. Fig. 3 is a side elevation ofwind-moving bellows and rigid brace.

(No model.)

In Fig. 1, E represents the reservoir; A B and A' B', the two pairs ofwind-moving bellows arranged on each side of the reservoir; C and C',the rigid braces connecting the bellows A B and A' B', respectively. Dand D' represent the pitman-rods, which are pivoted directly to therigid brace C and O'.

In Fig. 2, F represents the driving-shaft.

The operation oi' the device is as follows: W'hen the power applieddraws the pitman-rod D up it closes the bellows A and opens the bellowsB, and at the same time the pitmanrod D' acts to depress and elevatebellows A' and B', but at a slightly different interval ot' time, byreason of the difference of attachment of the pitma-n-rods to thedriving-shaft, the crank-bends of the drivin g-shaft to which thepitman-rods are connected being at right angles to each other.

I am aware that the Patent No. 197,048 granted to E. P. Needham,November 13, 1.87 7 describes a peculiar construction ot' automaticalmusical instruments and the means to operate the bellows in the same,consisting of a crank attached to the main shaft and a toggle connectingthe crank and bellows; but as my invention relates to organettes, and asI attach the main shaft by a pitman-rod directly to the brace whichconnects the pairs ot bellows, and arrange the bellows A and B and A'and B', in connection with the reservoir E, to secure durability andstrength in the instrument and an even exhaustion of air, all herein setforth as the peculiar qualities of this construction, I consider thatsaid Letters Patent do not embody my invention.

What I claim is- 1. In an organette or mechanical musical instrument,the combination, with the air-reservoir E, oi' the bellows A B A' B',arranged in pairs upon each side thereof and lengthwise ot' theinstrument, to operate substantially as and for the purpose set forth.

2. In an organette or mechanical musical instrument, the reservoir E andbellows A B A' B', arranged in pairs upon each side thereof, incombination with the rigid braces C O', pitman-rods D D', anddriving-shaft F, constructed and arranged to operate substantially asspecified.
